Standing on the tailgate of the pickup truck, Bachmann thanked a crowd of perhaps 150 for their work making phone calls and convincing caucus voters on her behalf. Her rhetoric was buoyant, and Biblically tinged.

“All the seeds that we have sown are about to be harvested,” Bachmann cried out, to cheers and whistles. “There is seed time and there is harvest. And tomorrow night is the harvest.”

Bachmann implored the crowd to post their photos on Facebook and Twitter, and to get out the vote with everyone they know.

“Tell your friends to multiply, multiply, multiply!” she said. “Tomorrow night we are going to see a miracle because we know the one who gives miracles. We can’t wait for tomorrow night. It’s going to be exciting.”

Then, after speaking for less than two minutes, she stepped off the tailgate and into the crowd for more personal greetings. Her Iowa campaign chairman, Brad Zaun, told The Register early-morning media appearances forced her to keep the night’s event short.

About 20 minutes after the campaign bus that brought her arrived, it was gone again.

Even after she left, though, supporters stayed behind, mingling, chatting, gathering up signs and picking at the remaining pizza and chips.

One supporter, Ron Sauer of Grimes, stuck around for the rally after a seven-hour shift calling voters for Bachmann. He said he liked her positions opposing illegal immigration and supporting the repeal of the Dodd-Frank financial regulatory reform law and the new federal health care.

In his calls this evening, Sauer described converting several independent voters to Bachmann’s side — a key demographic, he said.
